longest rear facing and cheapest!

Im sure this has been asked a billion times so I really appreciate your input.

My daughter turned 2 last week and has hit the height limit on her Safety 1st Complete Air... I've purchased 3 new seats for her so it's getting to be financially ridiculous. (infant seat, this one and one for my moms car)

I do not want to turn her FF but I cannt afford a crazy expensive seat SO wise car seat experts please tell me, what is the cheapest seat with the highest limits??

I think shes like 34 inches right now. Also I have a smallll car.

I dont mind spending a bit especially if I can use it for a few years but at this rate I want to know an expensive seat is going to last.

I have tried to research this but havent gotten too far so just thought I'd ask here, thank you!!

I'm sorry ... she has a Safety 1st Onside Air... not what I first said. It says in the manual rear-facing 19-32 inches. I should check her exact height also, probably would help to have my facts straight before making a post asking for help haha.
